Re: DDD on DSL Platform

Interesting and confusing. I'm not sure I agree with the definition of aggregate that is being used. Aggregate roots have to do with transactional boundaries, and may or may not consist of multiple entities and value objects. The DSL-platform however describes them as "containers for entities and value objects" and "aggregate root = view starting from an entity". Aggregates are not views.

What is interesting and confusing is that I'm not sure about the value of the DSL. I mean, it is readable, yes, but where does the logic go? What I'm seeing being generated are anemic models. Also, code generation usually results in some kind of worst-of-all-worlds solutions, and prevents the flexibility and limits the options that using a specific programming language has. Code generation usually only works on simple (CRUD) applications, on more complex systems it at best can only help by generate scaffolding.

My compliments on the effort, but right now I'm not intrigued.
